what are the volume of piece of chalk
[object Object]
Without knowing the density of an object, it's not possible to calculate it's volume by weight. A 1kg piece of granite and a 1kg piece of igneous rock would be very different in volume.
Iron pyrite (FeS2) has a density of 4.8 to 5.0 grams per cm3. A piece of volume 40 cm3 would, therefore have a mass of volume*density = 192 to 200 grams.
No, the 10g piece of aluminum and 10g piece of iron would not have the same volume. Different materials have different densities, so even if they have the same mass, their volumes will be different.
-- Get a pure piece of it. The size of the piece doesn't matter. -- Measure the mass of the piece. -- Measure the volume of the piece. -- The density of the substance is mass of the piece/volume of the piece.
Carbon Dioxide
22.5 grams, approx.
The gas is Carbon dioxide, formed by the decomposition of Calcium carbonate it the Marble or Limestone
Density = (mass) / (volume) = 2.1/14 = 0.15 gm/cc
The density of a piece of granite with a volume of 340 cm and mass of 918 g would be 1,400 grams. This is a math problem.
Weigh the piece of maple (you've indicated it is about 10 grams) Completely submerge it in a liquid and measure the volume of liquid displaced Density = mass/(volume displaced) or about 10g/(volume displaced)
